LIQUID-DISPENSING- APPARATUS.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application led February 2, 1907. Serial No. 355,457.

To all whom it may concern:

Be it known that we, VILLIAM C. MAYO and JOHN HoULEI-IAN, citizens ofthe United States, residing at El Paso, in the county of El Paso andState of Texas, have invented a new and useful Liquid-DispensingApparatus, of which the following is a specification. l

This invention has reference to improvements in liquid dispensingapparatus, and its object is to provide a means whereby beverages orother liquids may be obtained from the apparatus by a customer on thedeposition in the apparatus of a coin of proper value.

To this end the invention comprises a suitable receptacle for the liquidto be dispensed, means for ejecting from the apparatus a predeterminedquantity of the liquid, a locking means for preventing the operation ofthe apparatus except when a coin of the proper predetermined value hasbeen introduced, which coin will release the locking mechanism andpermit the liquid-ejectiiig mechanism to be manipulated by a customer toan extent sutlicient to cause the outow of the liquid in a predeterminedquantity.

The invention' further comprises a means for presenting` to the customerclean glasses or other liquid receptacles, and means whereby the usedglasses may be automatically cleansed and ultimately presented to futurecustomers, all by the operation of the machine in the act of ejectingthe liquid to a customer.

The invention further comprises means whereby the inserted coin isitself employed for the operation of the lock mechanism whereby theapparatus is released to the manipulation of a customer; and means areprovided whereby any attempt of an unscrupulous person to work themachine by a coin and then withdraw the latter will be .with the partsin position to illustrate one phase of the operation; Fig. 2 is asimilar chine; Fig. 3 is a cross section on the line Io-.9o of Fig. 1;Fig. 4 is a cross section on the line g/-g/ of Fig. l; Fig. 5 is asection of the coin conduit on the line e-z of Fig. 1;

Fig. 6 is a detail view of the operating pinion; Fig. 7 is a detailview, partly in section, showing a portion of the operating mechanismfor propelling the turn-table carrying the liquid-receiving receptacles;and Fig. 8 is a detail view of the coin-engaging end of the operatinglever handle section.

Referring to the drawings, there is shown a main casing 1 of cylindricalshape, the bottom of which is supported upon an annular foot 2 havingformed thereon so as to surround the base an annular trough 3 designedto receive waste liquid which will be permitted to escape through asuitable orilice, not shown. In the bottom of the casing l. andconcentric therewith is a punip cylinder l secured to the casing byscrews 5, or otherwise, and this pump cylinder has formed in one side aconduit 6 which coini'nunicates with the interior of the pump cylinderthrough an opening 7 at the lower end thereof. This conduit 6 iscontinued up above the pump cylinder and there carries a valve 8controlled by a spring 9, and the top of the conduit is closed by ascrew-cap 10 which also serves to confine the valve and spring in theconduit. Above the valve-seat the conduit 6 communicates with a spout 11screwed through the side of the casing into a boss 12 formed on the sideof the conduit 6.

lVithin the pump cylinder 4 there is a piston 13 provided with suitablepacking rings 1-1, and through this piston is a passage 15 in which islocated a Valve 16 provided with a valve head 17 seated in a suitablevalveyseat formed at the lower end of the'passage 15. The sten-i of thevalve 16 is guided b v a Ibracket 18 fast on the pistbn, and a spring"rod 21 near its lower end.

The casing 1 is designed to form avreceptacle for the liquid to bedispensed andalso for the coin-controlled operating mechanism of themachine. To separate the casing into a lower compartment forthe liquidand an upper compartment for the coin-controlled mechanism, the casingis divided into two parts, the upper part having its lower end closed bya diaphragm 24 provided with an annular flange 25 extending below saidupper part of the casing and there threaded so as to encrage threads onthe upper inner edgeof the ower or liquid-receiving portion of thecasing. This threaded connection is indicated at 26. In order that themechanism in the upper compartment of the casing may be readilyaccessible, the diaphragm 24 is held removably therein by screws 27, orotherwise.

At the center the diaphragm 24 is formed with a boss 28 through whichextends the piston-rod 21, land above this boss the pistonrod projectsupwardly into the upper chamber of the casing and is there provided withrack teeth 29 fora purpose which will hereinaf'ter appear. It will nowbe seen that if the piston be raised from the lowermost positionindicated in Fig. 1, liquid contained in the lower compartment of thecasing and at such a level as to ll the pump cylinder 4, will flowthrough the opening 15 and by the valve head 17 into the space below thepiston, and when the piston is again depressed the valve head 17 willclose this opening and the liquid will be forced up the conduit 6,opening the valve 8 and escaping through the spout 11, the pump being ofthe ordinary force-pump type.

Coming, now, to the mechanism shown in the upper compartment of thecasing, it will be seen that the'rack teeth 29 on the upper end of thepump piston engage a pinion 30 which, in turn, meshes with another rack31 fast to the inside of the casing by means of screws 32 and facingVthe rack 29 on the upper end of the piston-rod. This structure is suchthat any force applied to the axis of the pinion 30 to move the same ina vertical plane will, through the coaction of the two racks 29 and 31and the pinion 30, cause the rack 29 to travel through twice thedistance traveled by the axis of the pinion 30. Thus the pump may beoperated through the desired range of movement by a movement of thepinion axis through a path of only half the extent of movement of thepump piston.

For the purpose of moving the pinlon 30 through the desired range oftravel, there is provided a lever 33 pivoted coincident with the rackbar 31 by a pivot screw 34 entering a nut formed in said rack bar. Thislever 33 is perforated coincident with the axis of the pinion 30, asshown at 35, Fig. 4, and through this perforation extends the hub 36 ofa toothed wheel 37, which hub 36 constitutes the journal bearing ofthepinion 30 and to which the latter is heldY by a screwv In the path ofthe ratchet teeth 42 is a ratchet pawl 43 pivoted at 44 upon said pinion30 and under the stress of a spring 45, as indicated in Fig. 6. The endof the lever 33 re mote from its pivot point carries a section 46 of thecoin conduit, which section 46 is in one phase of the operation of themechanism coincident with and projecting into another section 47 of thecoin conduit formed as a part, and, if desired, an integral part, of thewalls of the upper compartment of the casing 1, and this section 47terminates at the uper end in a coin-receiving opening 48 exterior tothe machine.

Carried by the lever 33 and confined there* to by guide brackets 49-50is a slide bar 51 constrained by a compression spring 52 to normallytend in a direction away from the pivot point of the lever 33. Thespring 52 is confined in a recess 53 formed in the inner face of theslide bar 51 and abuts at one end against one wall of this recess and atthe other end against a lug 54 formed on the lever 33 and projectinginto the recess 53. This slide bar extends to the section 46 ot thecoin-conduit carried by the lever 33 and is there formed into a head 55having therein a vertical groove 56 coincident with the coin channelformed in the coin conduit section 46. This head 55 is, however, formedwith a cam face 57 in the path of the coin, and a recessed portion 58below the same constitutes a pocket for the coin as will hereinafterappear. The slide bar 51 also carries a block 59 in position to engagethe teeth of the toothed Wheel 37 when this lever has been moved by thespring 52 away from the pivot point of the lever 33, the said toothedblock also acting as a stop for limiting the movement of the slide barunder the action of the spring 52.

The lever 33 has an extension 6() beyond the coin conduit section 46 andthere is pivotally secured to it by means of a screw 61 an arm 62extending to the exterior of the machine. This arm 62 passes through aboss 63 formed on a sliding cover plate 64 closing a vertical slot 65formed in the wall of the casing 1 andconstituting a guideway for themovement of the arm 62, whereby the latter may have an extended verticalmovement but is prevented from lateral movement and, in turn, serves atthis point to guide the lever 33 of which. it constitutes an extensionor elongation. The arm 62 is les threaded at its outer end to receive acap 66 between which and the outer end of the boss 63 there is conned aspring 67. The arm 62 also receives in a nut formed in its outer end theshank 68 of a manipulating handle 69 located exterior to the machine inconvenient position for manipulation by a customer.

The inner end of the arm 62 is formed'into a cam head 70 eccentric tothe pivot screw 61, and this cam head enters the coin conduit section 46through a slot 71 formed therein opposite the head 55 formed on theslide bar 51. The arm 62 has a limited movement around the pivot screw61 determined by a slotted or hooked linger 72 formed on said arm andengaging a lug 73 formed on said coin conduit section 46 in the path ofsaid finger 72. Connected to the arm 62 within the casing there is aspring 74, the other end of which is fast to the top of the casing.There is also another spring 7 5 connected at one end to the lever 33and at the other end to the upper end of the piston-rod 21.

The normal position of the parts is shown in Fig. 1, that is, the pumppiston is at the lowerinost point of its travel and the lever 33 hasmoved downward until stopped by the engagement of the lug 73 with thediaphragm 24, while the spring 74, acting on the arm 62, maintains it ina slightly elevated position a little above the lower edge of vthe slot65, with the cam head 7 0 projecting into the coin conduit section 46opposite the head 55 on the slide bar 51, the two arts 55 and 70coacting to restrict the width of the coin conduit at this point. Now,if a coin be dropped through the opening 48, it will gravitate to thisrestricted portion of the coin conduit, but if the handle 69 bedepressed against the action of the spring 74 the arm 60 will be turnedon its pivotv 61, carrying the cam head 70 out of the conduit, so thatthe coin may now drop until arrested by a stop 76 formed on thediaphragm 24, and when the parts are in the position shown in Fig. 1this stop 76 enters the lower end of the section 46 of the coin conduitsu'liiciently to hold the coin in line with the recess 5S in the headformed on the end ot' the slide bar 51. Now, if the handle 69 be movedupward, by the action of the spring 74 and by the hand of a customer,the cam head 7 0 will again enter the coin conduit section 46 and engagethe coin, forcing it against its seat on the head 55 and ultimatelycausing the bar 51 to be moved longitudinally to a suiiicient extent tocarry the toothed lug 59 out of engagement with the toothed wheel 37.The pinion 30 is now unlocked and the handle 69 may be raised to thefull extent of its travel and thus, through the action of the fixed rack31 and the pinion 30, raise the piston-rod 21 and the piston 13 to theupward limit of their movement, as shown in Fig. 2, this upward limit oftravel being determined by the position of the upper edge of the slot 65wvhich is then engaged by the arm 62. The customer' now presses downupon the handle 69 and because of the resistance oi':1 the liquid, whichhas in the meantime flowed through the valve in the piston to the underside of the latter, the first downward movement of the handle will causethe arm 62 to turn on its pivot and carry the cam head 70 away from thecoin, thus permitting the coin to fall from out the movable section ofthe coin conduit. The slide bar 51 now returns to its lirst positionunder the action of the spring 52 and the toothed block 59 engages andlocks the toothed wheel 37. But the pinion 30 is still free to move uponits axis since the pawl 43, which holds the pinion against movement onthe hub 36, is inactive to the movement of the pinion in a direction tolower the piston. However, as soon as the handle 69 has again beenlowered to the position shown in Fig. 1, the pawl 43 and ratchet teeth42 coact with the toothed wheel 37 and toothed block 59 to eHectuallylock this pinion against return movement and so lock the entirestructure against further manipulation until another coin of the properdenomination has been inserted.

In theoperation thus far described it has been assumed that the user issupplied with a suitable receptacle for the liquid ejected through thespout 11` But the invention contemplates means whereby clean glasses, orother suitable receptacles, may be carried by the machine for theconvenience of the user. For this purpose there is formed on or securedto the lower portion of the casing 1 an annular flange 77 between whichand a shoulder 7 8 higher up on the casing is mounted an annular casting79 made hollow, as shown, for lightness, and this casting is formed atits lower end with an annular, horizontally n projecting glass carrierS0. Upon the upper edge ot' the casting 79 there is formed an annularledge 81 carrying an annular series of ratchet teeth 82 the purpose ofwhich latter will be hereinafter described. The flange 7 7 carries anumber of equi-distantly spaced hollow uprights 83, each having a numberof upwardly-projecting nozzles 84, and the top of each uprightterminates in a pin 85 upon which is hung a glass tumbler 86 bottomupward, tbe lower edge of the glass hanging close to the upper face ofthe glass-carrier 8O within an upturned rim 87 formed on the edge of theglass-carrier. The interior of each of the hollow uprights 33communicates with a duct S3 extending through the'base of theglass-carrier to a point above the flange 77, and in this flange 77there is formed a passageway 89, open on its upper edge so as to be incommunication with the inner ends of the ducts 88. The passageway 89extends through but a portion of the circumference of the flange 77, sayto the extent of about ninety degrees. The ducts 88 will therefore be incommunication with this Apassageway through but one-quarter of therevolution of the glass-carrier, which latter, in the practicaloperation of the machine, is made to travel entirely around its seat onthe flange 7 7.

Water is conveyed to the passageway 89 from a source of supply notshown, and when one or more of the ducts 88 is in communication withsaid passageway 89 the water is conveyed through thel hollow uprights 83and forced through the nozzles 84 against the sides of the glasstumblers. These nozzles 84 are given a slight twist, so that the waterjets will strike the inner walls of the tumblers more or lesstangentially and produce a swirl of the water which is very efficient incleansing the inside of the glass. The water used for washing theglasses falls on to the bottom of the glass-conveyer, which is purposelymade slightly inclined toward the axis of the conveyer, and a number ofpassages 90 are provided to convey the waste water into the trough 3from which it may be conveyed away in any suitable manner, as by meansof a waste pipe which, however, is not shown.

The glass-carrier is covered by a hood 91, fast in any suitable mannerto the casing, and which extends around the said glasscarrier exceptadjacent to the spout 11, so that the glasses are hidden from view whilebeing cleansed, and only the one about to be used is within the reach ofthe customer.

The passageway 89 is made to extend through only about a quadrant, sothat the glasses will have time to vdrain and dry before they arebrought into reach of the customer. In order to prevent the escape ofwater between the passageway 89 and the edges of the glass-carrier, themeeting edges of the glass-carrier and the flange 77 may be ground toproduce a water-tight joint.

In order to provide for the rotation of the glass-carrier, the lever 33is formed with a short arm 92 to which is secured a link 93 carrying apendent pawl 94, the lower end of which is formed with a tooth 95engaging the rack teeth 82 on the ledge 81 before referred to. The pawl94 passes through and is guided in the upper wall of the hood 91, andthis portion of the structure is protected by a casing 96 fast to thecasing 1 and the hood 91, as indicated in F ig. 1. Now, when the lever33 is moved to raise the piston 13 the outer end of the arm 92 isdepressed and through the link 93 depresses the pawl 94, which, in itsnormal position, rests behind a tooth 82 at a slight angle to thevertical, so that as a result of the downward movement of the arm 92 andlink 93, the lower end 95 of the pawl 94 will be forced in Aa directionto rotate the the upper section 47 of the coin conduit is provided witha cross slot 97 in which moves a knife blade 98 fast to one end of arock arm 99 pivoted at the other end to the diaphragm 24 and in the pathof a lug 100 on the arm 62 of the' manipulating lever, so that as thislever is movedy the knife will be forced across the conduit and therebysever any cord or wire which may have been attached to the coin, beforethe lever can be manipulated to cause the machine to expel the liquid.

For the purpose of notifying an observer of the amount of liquidcontained in the lower compartment 0r liquid reservoir, a float 101 isprovided therein having attached thereto an indicator arm 102 arrangedopposite a window 103, whereby the level of the liquid in the reservoirmay be at once ascertained and the intended purchaser may thereby knowwhether or not the reservoir contains sufficient liquid to supply thenormal operation of the machine.
